Electronic apparatus

An electronic apparatus comprising:

• a noise generation source that generates electromagnetic noise;
• and
• a housing made of a conductive material and accommodating the noise generation source, wherein
• the housing includes first and second housing components defining an accommodation space for accommodating the noise generation source,
• the first housing component includes first fixing parts fixed to the second housing component, and at least two ridge parts protruding toward the second housing component and extending in directions away from the first fixing parts,
• the second housing component includes second fixing parts, each of which is fixed to a corresponding one of the first fixing parts of the first housing component, and at least two grooves extending in directions away from the second fixing parts and into which the two ridge parts enter,
• the ridge parts and the grooves each have a protrusion amount and a depth that make a resonance frequency of the housing different from a frequency of the electromagnetic noise,
• wherein
• two of the first fixing parts are arranged diagonally on the first housing component, and
• two of the second fixing parts are arranged diagonally on the second housing component.
